Default Final Drive Ratios

I have a question.

I have a 99 SSEi with the 4T65-E and at 68mph it turns 2,000 RPM. I also have a 99 GP GT, and at 70 it turns about 2,200-2,300 RPM. Now, it goes into overdrive and lockup so no probs there (infact the tranny was just rebuilt 2k ago). Just wondering what the differences in final drive were.
